Benefits of technology

The patent text describes an ink jet recording method that uses a recording medium with a low nonpolar component of surface free energy. This method allows for the high-speed manufacturing of recorded matter that does not bleed. The technical effect of this is the ability to produce quality printed materials that do not bleed, even when using a recording medium that has a low nonpolar component of surface free energy.

Problems solved by technology

However, in the recording method used in the related art, it is difficult to form an image at high speeds while sufficiently preventing bleeding of the ink depending on the type of medium.

example 1

[0142]First, the ink composition (first ink composition) is prepared as below.

[0143]Water, C.I. Pigment Blue 15:3 (average particle size: 100 nm) as a resin dispersed pigment, resin particles (glass transition point: 20° C., average particle size: 100 nm) configured by a styrene-acrylic copolymer, 1,2-hexanediol as the alkane diol with 4 or more to 8 or fewer carbon atoms, glycerin, and triethanolamine as amine derivative were mixed, and an ink composition (first ink composition) was obtained.

[0144]Next, the ink composition (first ink composition) prepared as above was filled in the interior of a discharge head (resolution per unit length: 360 dpi) using a piezoelectric element attached to an ink jet recording method printer PX-G930 (manufactured by Seiko Epson). After filling, the ink composition is applied with respect to the recording medium described in Table in a predetermined pattern, and a recorded matter is obtained.

[0145]Moreover, the recording medium A below is used as the...

[0147]By adjusting the type and usage amount of the components used in the preparation of the ink composition, the constitutions shown in Table were prepared and further, other the using the recording medium shown in Table, a recorded matter was manufactured similarly to Example 1.

[0148]Moreover, recording medium B is a film-based matte paper (MC Matte Synthetic Paper, manufactured by Seiko Epson) including an absorbing layer, the nonpolar component γsd of the surface free energy is 19.6 mN / m, and the polar component γsp of the surface free energy exceeds 20 mN / m.

[0149]Recording medium C is a recording paper (Xerox 4200, manufactured by Xerox), the nonpolar component γsd of the surface free energy is 26.3 mN / m, and the polar component γsp of the surface free energy is 0.3 mN / m.

[0150]Recording medium D is a recording paper (Xerox P, manufactured by Xerox), the nonpolar component γsd of the surface free energy is 38.2 mN / m, and the polar component γsp of the surface free energy is 3.7...

example 11

[0152]In Example 11, the ink composition disclosed in Example 1 was used as the first ink composition, and furthermore, outside of use together with the ink composition disclosed in Example 4 as the second ink composition, a recorded matter was prepared similarly to Example 1.

Comparative Examples 1 to 4, Reference Examples 1 and 2

[0153]Other than using the ink composition and recording medium as shown in Table, the recorded matter is manufactured in the same manner as Example 1.

Abstract

An ink jet recording method includes discharging a first ink composition onto a recording medium using a recording head, in which the first ink composition includes a coloring material, an alkane diol with 4 or more to 8 or fewer carbon atoms, a water-soluble solvent, and water; the recording head discharges the first ink composition using a piezoelectric element, and has a resolution per unit length of 200 dpi or more, and the recording medium has an absorbing layer on the surface thereof, in which a nonpolar component of a surface free energy of the absorbing layer is 20 mN / m or lower.

Description

[0001]Priority is claimed under 35 U.S.C. §119 to Japanese Application No. 2013-059555 filed on Mar. 22 2013, is hereby incorporated by reference in its entirety.BACKGROUND[0002]1. Technical Field[0003]The present invention relates to an ink jet recording method and a recorded matter.[0004]2. Related Art[0005]There is demand for an ink with a low viscosity in ink jet methods in which ink is discharged as minute droplets. On the other hand, because it is necessary to prevent bleeding of the ink on a recording medium, an ink jet ink that includes a penetrant is used (for example, refer to JP-A-2001-187850).[0006]However, in the recording method used in the related art, it is difficult to form an image at high speeds while sufficiently preventing bleeding of the ink depending on the type of medium.SUMMARY[0007]An advantage of some aspects of the invention is to provide an ink jet recording method able to manufacture at high speeds a recording matter having a printing portion in which b...
